Embedded samples with Kotlin/Wasm

[manuel-martos]

Description

As we're now supporting Kotlin/Wasm as a new Web target, we can transition all embedded samples from JS to Wasm. These changes have been implemented under this Pull Request (PR):

• Ensure all Web samples compile seamlessly with Kotlin/Wasm.
• Update documentation and incorporate new tasks for building samples with Kotlin/Wasm.
• Revise the CI workflow to accommodate the generation of documentation.
• Remove the Kotlin/JS target from web samples along with any unused code.

Checklist

• I've updated CHANGELOG.md if required.
• I've updated the documentation if required.
